Give examples of the use of irony in the novel Oliver Twist?

Examples of Irony:

If he could have known that he was an orphan, left to the tender mercies of church-wardens and overseers, perhaps he would have cried the louder.

For the combination of both these blessings in the one simple process of picking oakum, Oliver bowed low by the direction of the beadle, and was then hurried away to a large ward; where, on a rough, hard bed, he sobbed himself to sleep. What a novel illustration of the tender laws of England! They let the paupers go to sleep!
